Wed, 26 Jul 2023 01:59:26 +0200

arm64 lib32: prepare arm64 headers to redirect to armIn order to compile lib32 libraries and other 32-bit code on arm64, needs to be redirected to an arm header ratherthan arm64 when building with -m32. Ifdef the arm64 headers thatare installed in /usr/include/machine and used by user-level software(including references from /usr/include/*.h) so that if __arm__ isdefined when including the arm64 version, is includedrather than using the rest of the file's contents. Some arm headershad no arm64 equivalent; headers were added just to do the redirection.These files use #error if __arm__ is not defined to guard againstconfusion. Also add an include/arm Makefile, and modify Makefilesas needed to install everything, including the arm files in/usr/include/arm. fenv.h comes from lib/msun/arm/fenv.h.The new arm64 headers are: acle-compat.h cpuinfo.h sysreg.hReviewed by: jrtc27, impDifferential Revision: https://reviews.freebsd.org/D40944 List of files: /freebsd/sys/arm64/include/counter.h

a2a0f90654eeca563cf47f043d6c1a14e6a7e289 - Centralize __pcpu definitions.

Thu, 29 Aug 2019 09:25:27 +0200

Centralize __pcpu definitions.Many extern struct pcpu __pcpu declarations werecopied/pasted in sources. The issue is that the definition is MD, butit cannot be provided by machine/pcpu.h due to actual struct pcpudefined in sys/pcpu.h later than the inclusion of machine/pcpu.h.This forced the copying when other code needed direct access to__pcpu. There is no way around it, due to machine/pcpu.h supplyingpart of struct pcpu fields.To work around the problem, add a new machine/pcpu_aux.h header, whichshould fill any needed MD definitions after struct pcpu definition iscompleted. This allows to remove copies of __pcpu spread around thesource. Also on x86 it makes it possible to remove work arounds likeOFFSETOF_CURTHREAD or clang specific warnings supressions.Reported and tested by: lwhsu, bcranReviewed by: imp, markj (previous version)Discussed with: jhbSponsored by: The FreeBSD FoundationDifferential revision: https://reviews.freebsd.org/D21418 List of files: /freebsd/sys/arm64/include/counter.h

ab3059a8e7f382cff93dbe4d1b082adf62f4d849 - Back pcpu zone with domain correct pages

Fri, 06 Jul 2018 04:06:03 +0200

Back pcpu zone with domain correct pages- Change pcpu zone consumers to use a stride size of PAGE_SIZE. (defined as UMA_PCPU_ALLOC_SIZE to make future identification easier)- Allocate page from the correct domain for a given cpu.- Don't initialize pc_domain to non-zero value if NUMA is not defined There are some misconceptions surrounding this field. It is the _VM_ NUMA domain and should only ever correspond to valid domain values as understood by the VM.The former slab size of sizeof(struct pcpu) was somewhat arbitrary.The new value is PAGE_SIZE because that's the smallest granularitywhich the VM can allocate a slab for a given domain. If you havefewer than PAGE_SIZE/8 counters on your system there will be somememory wasted, but this is obviously something where you want thecache line to be coming from the correct domain.Reviewed by: jeffSponsored by: Limelight NetworksDifferential Revision: https://reviews.freebsd.org/D15933 List of files: /freebsd/sys/arm64/include/counter.h

Mon, 17 Apr 2017 19:34:47 +0200

- Remove 'struct vmmeter' from 'struct pcpu', leaving only global vmmeter in place. To do per-cpu stats, convert all fields that previously were maintained in the vmmeters that sit in pcpus to counter(9).- Since some vmmeter stats may be touched at very early stages of boot, before we have set up UMA and we can do counter_u64_alloc(), provide an early counter mechanism: o Leave one spare uint64_t in struct pcpu, named pc_early_dummy_counter. o Point counter(9) fields of vmmeter to pcpu[0].pc_early_dummy_counter, so that at early stages of boot, before counters are allocated we already point to a counter that can be safely written to. o For sparc64 that required a whole dummy pcpu[MAXCPU] array.Further related changes:- Don't include vmmeter.h into pcpu.h.- vm.stats.vm.v_swappgsout and vm.stats.vm.v_swappgsin changed to 64-bit, to match kernel representation.- struct vmmeter hidden under _KERNEL, and only vmstat(1) is an exclusion.This is based on benno@'s 4-year old patch:https://lists.freebsd.org/pipermail/freebsd-arch/2013-July/014471.htmlReviewed by: kib, gallatin, marius, lidlDifferential Revision: https://reviews.freebsd.org/D10156 List of files: /freebsd/sys/arm64/include/counter.h

Update arm and arm64 counters MD bits.On arm64 use atomics. Then, both arm and arm64 do not need a criticalsection around update. Replace all cpus loop by CPU_FOREACH().This brings arm and arm64 counter(9) implementation closer to currentamd64, but being more RISC-y, arm* version cannot avoid atomics.Reported by: Alexandre Martins Reviewed by: andrewTested by: Alexandre Martins, andrewSponsored by: The FreeBSD FoundationMFC after: 2 weeks List of files: /freebsd/sys/arm64/include/counter.h

Bring in the start of the arm64 kernel.This is only the minimum set of files needed to boot in qemu. As such it ismissing a few things.The bus_dma code is currently only stub functions with a full implementationfrom the development tree to follow.The gic driver has been copied as the interrupt framework is different. Itis expected the two drivers will be merged by the arm intrng project,however this will need to be imported into the tree and support for arm64would need to be added.This includes code developed by myself, SemiHalf, Ed Maste, and RobinRandhawa from ARM.
